Abstract: A diaphragm driven vitrectomy probe employing multiple diaphragms. The probe includes multiple diaphragms providing added areas to which hydraulic air may be delivered in reciprocating a cutter of the probe. Thus, the diaphragms and the probe housing may be reduced in size without sacrifice to force driving cutter reciprocation. Additionally, the amount of force attained and the rate of cutter reciprocation may be increased through the use of multiple diaphragms. Alternatively, the use of added diaphragms may allow for the rate of cutter reciprocation to be maintained even while the air pressure utilized may be reduced.
